Autoload the function instead of declaring it directly.

perform like `command ls`.
Refactored code to use more zsh extensions like globbing instead of
parsing the output of `ls` making it a lot faster.
Add unbkp() that reverses bkp().
Use shorter zsh syntax for disowning a background job.
Add usage string to mangrep.
Expect clang-format config to be in XDG_CONFIG_HOME. Add functionality
of comments.
Use `command` where we want a command to be taken as external.
